While HEPA filtration is considered the gold standard for air purification, the Air Genius purifiers go one step further with the ifD filtration technology.

It is considered to be one of the best techniques for air cleaning, making use of permanent washable filters.

The first layer of filtration is the washable pre-filter that tackles the larger airborne particles. It is attached to the rear grille and also traps odors and VOCs at this stage.

Next comes the patented ifD filter uses electronic filtration to capture particles with a 99.9% efficiency.

These filters are permanent and can be simply rinsed or washed clean. No microscopic pollutants can escape this level of filtration.

Lastly, the electronic ionizer boosts the cleaning power of the air purifier. When the air purifier is turned on, large volumes of air are drawn towards the filter.

It may help to vacuum the surrounding areas to prolong the life of the filter.


Filter Change, Repairs, and Warranty

Filter Change Requirements

The best feature of the Compact Air Genius 4 is perhaps the fact that its permanent ifD filter can simply be rinsed in water for cleansing.

When it comes to pre-filters, the users have two options to choose from. They can either go for yet another permanent washable filter or a replaceable filter known for odor and VOC reduction.

The replaceable filters for odor reduction can be purchased at

They are useful in deodorizing the air and should be replaced every three months for the best results.

The ‘check filter’ light present on the air purifier will go off, and you will simply need to clean out the filter by washing it.

It eliminates the need for periodically purchasing replacement filters and costing the additional buyer money in the process.

Repairs and Warranty

Honeywell provides the most prolonged warranty period of 5 years on the Compact Air Genius 4 as well as its permanent ifD® filter.

The warranty covers any defects in material or workmanship, but the replacement pre-filters are excluded from the same.

Price of Honeywell Compact Air Genius 4 and Its Filters

The Honeywell Compact Air Genius 4 has incorporated an ingenious ifD® filter that is permanent and washable.

This means that unlike other filters where you have a fixed annual cost in terms of filter replacement, the replacement charge is entirely absent in this model.

The filter that is fitted in the unit will last for as long as the unit itself with proper care and maintenance.

In our opinion, this feature makes the Honeywell model much more advanced as compared to other air purifiers, and hence it is reasonably priced even though it is a bit higher than its counterparts.


Who Should Buy Honeywell Compact Air Genius 4 ?

Why We Like It

Honeywell is one of the most recommended brands by doctors and allergists.

The Air Genius 4 model is straightforward to use, and the four corroborates with the four pre-set levels of the air purifier, namely – Sleep, General, Allergen, and Max.

You can use the extra-sensitive Allergen mode, which comes handy during spring and fall time if you are plagued with allergies.

Even when the purifier is operated at the Max mode, it is barely audible.

With such elegant design upgrades, the Honeywell Compact Air Genius 4 wins our vote for an excellent air purification solution!
